Title: Pulse width modulated motor control system - has two current sources of opposite polarity, one with higher voltage than other
Inventor: SCHMIDT ROBERT H
IPC: H02M3/156
Filed: 1976-09-17
Abstract: Pulse width-modulated system for controlling a reversible d.c. motor or an inductive impedance comprises a source of pulse width-modulated signals of opposite polarity and variable width, two current control means with terminals connected to the signal sources in a complementary structure, and two current sources of opposite polarity, one with a higher voltage. Switch means are connected to the current control device in such a way that actuation of one current control devices connects up one current source to supply the load with energy, and actuation of the other connects up the other current source. The circuit thus forms an asymmetrical bipolar system using different energy supply levels to drive the motor forwards and backwards.

Title: Fan operated cooker oven with pyrolytic cleaner - has switch protecting fan motor by reducing speed or heating power
Inventor: KLEMENT JOHANN
IPC: F24C15/32
Filed: 1976-12-21
Abstract: The cooker oven has electric motor driven fan for circulating hot air. The oven has also means for pyrolytic cleaning. The electric motor is protected efficiently against damage by high temp. A control system ensures that the fan speed or the heating power is reduced at certain threshold temp. The drive motor (3) of the fan (8) has electrical resistor Rv for speed reduction. The resistor is operated directly or indirectly by a thermally actuated switch (S2). The parallel current flow path which bypasses the resistor accommodates the thermally actuated switch and its series connected manually operated switch (S1). The fan heating system is connected in series with the cooker oven heater at an oven threshold temp.

Title: Drilling rope winding system - with ropes leading from dead=end fixtures over derrick and hook pulleys to winch drums
Inventor: POHL ARNOLD VON
IPC: E21B19/02
Filed: 1977-01-14
Abstract: A rope winding system for drilling plant with a derrick consists of two ropes which raise and lower a pulley block with the load hook. Each rope is led from a dead-end fixture at the ends of a balance beam over pulleys at the top of the derrick to one of the two pulleys of the pulley block. This results in higher load velocities for the same drilling rope velocity. The detrimental torsional loads of the derrick are reduced to a minimum.

Title: Communications system with synchronised scrambler - determines whether start code for received identifying character has been stored
Inventor: BOSCH SIEGFRIED
IPC: H04K1/02
Filed: 1977-05-20
Abstract: The communications system uses synchronised scramblers generating identical pseudo-random pulse trains. A first station checks the identifying character received from a second station and determines whether the start code for this character has been stored. It is has been stored then both stations use the start code associated with this character to set the scrambler generators. If the best result is negative the first station automatically transmits a code synchronising pulse sequence to the second station.

Title: Screw=in stud for sports shoes, football boots etc. - is double-layered plastics stud with softer outer casing surrounding metal shaft
Inventor: MOELLER GUSTAV
IPC: A43C15/16
Filed: 1977-07-27
Abstract: The plastics stud which encases the metal threaded shaft is made in two layers so that it has an inner core of hard plastics e.g. polyamide, polystyrene and an outer casing of relatively soft wear-resistant plastics such as polyurethane. The hard plastics core provides a good connection with metal threaded pin whilst the relatively soft outer casing which can be easily bonded with the hard core avoids danger or injury to other players. Although the outer casing can be bonded by injection moulding round the hard core a positive connection can also be provided if the core has projections which engage in indentations in the outer casing. The hard core can have apertures running parallel to the screw-in axis which can then be filled with the softer plastics of the casing.

Title: Anisotropic sheet mfr. from resin bound and compressed grains - to obtain low density, resilient or insulating paper or board
Inventor: ARGUILLERE JEAN
IPC: D06N7/00
Filed: 1977-08-18
Abstract: Sheet materials out from tubular stock are made by lay-up of a mixt. of fibrous granules and a binder resin with partial flattening of the granules by axial or radial compression prior to hardening the binder. The mixt. of resin and granules may be laid up in successive layers either within a cylindrical mould, suitable for applying axial compression, or round a mandrel, suitable for applying radial compression. Suitable for mfr. of thick or thin sheet, esp. alternatives to asbestos paper as an acoustic barrier beneath floor tiles or where a high specific stiffness (stiffness/wt. ratio) is required. Natural granules maintain multiaxial fibre orientation internally and an intrinsic flexibility and elasticity better than sheets fabricated from individual chopped fibres. Uniform distribution of low binder resin conons, is more readily attained. The direction and degree of anisotropic stiffness is more readily reproduced and controlled by the direction and degree of compression of the original granules.

Title: Instrument landing system with computer - compares altitude and distance from certain point with nominal values, and displays deviations
Inventor: HOEFGEN GUENTER DR ING
IPC: G01S1/08
Filed: 1977-09-12
Abstract: The system has a ground station radiating glide path and landing course signals, and a board station which derives from these signals the glide path and the landing course. It displays deviations both from the glide path and the course. In order to choose a freely selectable glide path (6) the board station (4) has in addition a range finder, a computer and at least one altimeter. At great distances from the landing strip (7) and during flattening out the glide path (6) is determined by the distance from the aircraft to a point near or on the landing strip (7), and by the measured altitude. At middle distances the glide path (6) is determined by the glide path signals. Values measured on board are compared by the computer with nominal values for the selected landing path, and deviations are displayed.
